Looking at my expert page, I don't see the "Add to Your Experts Network" or "Contact the Expert" buttons that I see on other people's pages, even though I have all my networking options enabled. What's the problem?

Don't worry - these links will appear for any other expert viewing your page (and you can see them yourself if you log out). They just won't appear when you're logged in as yourself, as you have no need to contact yourself.
